In a statement Rangers said they were disputing the invoice. It said: "not all of the invoices submitted with regard to this bill are legitimate."

Rangers also said they would defend any legal action brought by Orlit "vigorously".

BBC Scotland understands Orlit Enterprises are considering raising a winding up order against the company which currently runs Rangers within the next seven to 10 days, if the dispute continues.

Orlit Enterprises is run by the Singapore-based businessman Chan Fook Meng. He is a former business associate of the current Rangers chief executive Charles Green.

If Orlit wish to instruct their lawyers to go to court then we will defend our position vigorouslyRangers statement

In a statement on their website, Rangers said they had "been disputing a payment to a foreign company, Orlit, although it should be stressed we have never said there is no bill to be met. What we have said and what we are telling our supporters is that not all of the invoices submitted with regard to this bill are legitimate".

It continued: "There is no threat of this Club being closed. That is downright malicious and ludicrous. But let's make one thing clear: If Orlit wish to instruct their lawyers to go to court then we will defend our position vigorously.

"We do pay our bills on time and we have always been prepared to pay this one."
